Data were weighted to reflect the general U.S. population according to several variables (age, gender, race/ethnicity, education, income, level of physical activity, and number of 5-17 year old children in the household). Differences in steps per day between sub-groups were analyzed using unpaired t-tests when only two subgroups were involved, or one-way ANOVAs if multiple sub-groups were involved.RESULTS: Adults reported taking an average of 5,117 steps per day. Male gender, younger age, higher education level, single marital status, and lower body mass index (BMI) were all positively associated with steps per day. Steps per day were positively related to other self-reported measures of physical activity and negatively related to self-reported measures of physical inactivity. Living environment (urban, suburban, or rural) and eating habits were not associated with steps per day.CONCLUSIONS: In the current study, men and women residing in the U.S. accumulated fewer steps per day than those living in Switzerland, Australia, and Japan. Based on these findings, we conclude that low levels of ambulatory physical activity are contributing to the high prevalence of adult obesity in the U.S.This research was partially supported by NIH grant DK42549Pedometer-Measured Physical Activity and Health Behaviors In U.S. Adults: 2380: Board #259 June 3 2:00 PM - 3:30 PMBassett, David R.
